Mike, further to my last, if you run each circuit separately and test as you go you can save yourself a lot of headaches later on.

I "roughed in" the whole system before tidying it all up and making the final connections etc. Its a great confidence booster to fire up each circuit oine at a time and see that your workmanship actually works. Remeber too that Fords have a positive ground system as well or else you'll be in trouble...
